CR’s take: The Cuisinart Coffee on Demand is a self-serve model. It stores 12 cups of brewed coffee in a reservoir and has a dispenser instead of a carafe. It makes sense in homes where people are drinking coffee at different times; it keeps coffee hot and ready, so family and guests can fill their own cups. This model is programmable and features a water filter and a cleaning indicator. The reservoir can be removed for washing. In our tests, the Coffee on Demand performs quite well, receiving a Very Good rating for convenience. At less than $100, it can be a terrific choice for entertaining.
“What I REALLY like about it is that it’s pretty much an all-in-one system without the thousand-dollar-plus all-in-one cost. I push one button and all the magic happens, and it’s quite entertaining to watch the espresso cascade through the milk and create separate layers. I also like that I can take the milk and store it in my fridge. I’ve done some temperature tests, and only noticed a five-degree increase after making a double latte, before I put it back in the fridge. This is nice, as you would think that to be so close to all that heat, it would be a much bigger temperature fluctuation.”
Other coffee brewing devices became popular throughout the nineteenth century, including various machines using the vacuum principle. The Napier Vacuum Machine, invented in 1840, was an early example of this type. While generally too complex for everyday use, vacuum devices were prized for producing a clear brew, and were popular up until the middle of the twentieth century.
An early variant technique, called a balance siphon, was to have the two chambers arranged side-by-side on a sort of scale-like device, with a counterweight attached opposite the initial (or heating) chamber. Once the near-boiling water was forced from the heating chamber into the brewing one, the counterweight was activated, causing a spring-loaded snuffer to come down over the flame, thus turning "off" the heat, and allowing the cooled water to return to the original chamber. In this way, a sort of primitive 'automatic' brewing method was achieved.
The illy name is most often associated with their coffee, but they also make capsule-style machines for convenient home brewing. This model takes less space than the similar Y3 model, but still has features that coffee lovers look for. It brews standard drip coffee, and it makes espresso with 19 bars of pressure. No matter what you’re brewing, you can choose your brew strength, water temperature, and cup size, for the perfect cup every time.
Throughout the latter part of the 20th century, a number of inventors patented various coffeemaker designs using an automated form of the drip brew method. Subsequent designs have featured changes in heating elements, spray head, and brew-basket design, as well as the addition of timers and clocks for automatic-start, water filtration, filter and carafe design, and even built-in coffee grinding mechanisms.
When it comes to features, our top pick’s little sister, the OXO On 9-Cup Coffee Maker, looks and feels much the same: a single-button dial, programmable start times — even the timer that lets you know how old the coffee is after it’s been brewed is identical. On this version, the water reservoir isn’t detachable, but it brews coffee significantly faster than the 12-cupper’s 14 minutes(!) and it’s $100 cheaper. It’s a great machine that didn’t earn our top spot simply because the coffee it makes didn’t perform quite as well as the other three top picks in our taste tests, and it doesn’t let you tinker with water temperature and extraction the way the larger machine does.
Our top pick is the OXO On 12-Cup Coffee Brewing System. It’s a large machine – both in footprint and in capacity — but it earned the second-highest scores in our taste test, and is sleek both to look at and to operate. Convenient features like programmable auto-brewing, a removable water reservoir that doubles as a kettle, and a spigot that stops the brew mid-stream if you remove the carafe make this machine feel high tech without being high maintenance. For those who want to be a little more hands-on with the brewing process, its single-button dial also lets you adjust the water’s brewing temperature, giving you more access to experiment with extraction and flavor.
Regardless of whether you buy extra accessories, it's still very affordable, and you're really buying this machine for the espresso. The De'Longhi delivers in that regard. It's a 15 bar machine with a self-priming function, so you don't have to go through the hassle of prepping the machine. The 35oz water tank is removable for cleaning and it has a drip tray to catch spills. and a durable, high-quality stainless steel boiler to ensure many years of delicious espresso.
Only two optional settings are available: You can control the heating element under the carafe and turn down the temperature if desired. Other than that, the Moccamaster doesn't have—and doesn't need—anything else. Technivorm boasts that its heating element can get water between 196ºF and 205ºF, which specialists say is the ideal temperature for brewing coffee.

Our brew-performance tests measure the brew temperature and contact time (how long water stays within a sweet spot of 195° to 205° F for brewing). We measure concentration using a refractometer, a device that measures the amount of coffee dissolved in each brew. Our convenience tests look at how easy it is to set timers, fill the reservoir, clean the machine, and more. And for the first time, we’re incorporating predicted reliability and owner satisfaction ratings into the new Overall Score for each model. We determine these ratings for each drip coffee maker brand using survey data collected from thousands of CR members.
